Description

Technical Field

[0001] The invention relates to the technical field of forging equipment, in particular to a disc forging workbench. Background Art

[0002] Forging is a combination of forging and stamping. It is a forming method that uses the hammer, anvil, punch or die of a forging machine to apply pressure to the blank to cause plastic deformation, thereby obtaining a part of the desired shape and size. A forging refers to a workpiece or blank obtained by forging and deforming a metal blank.

[0003] In the prior art, the disc-shaped forging parts are mostly positioned by an arc plate, and the lower die is driven by a connecting rod to carry out material removal. However, in actual use, when the pressure of the arc plate on the workpiece is too large, the workpiece may not fall off in time during the movement of the lower die. Moreover, with the long-term friction between the workpiece and the workbench, this phenomenon becomes more serious, and the workpiece cannot be accurately removed from the workbench. Summary of the invention

[0004] The object of the present invention is to provide a disc forging workbench to overcome the above-mentioned defects in the prior art.

[0005] A disc forging workbench according to the present invention comprises a forging table, wherein the upper end of the forging table is provided with a stamping power source, the lower end of the stamping power source is connected to a telescopic gas rod, the lower end of the telescopic gas rod is connected to a forging block, the upper end surface of the forging table is fixedly provided with a circumferentially uniformly distributed limiting arc plates, each of the mutually close parts of the limiting arc plates is provided with a sliding box, a sliding cavity is provided in the sliding box, a support rod is slidably matched in each of the sliding boxes, a stripping block is fixed on the support rod, and a clamping block is provided at the end of the forging block when the stripping block approaches. The circumferentially arranged stripping block and the clamping block have end faces close to the forging block that are both arranged in arc surfaces, and the abutting parts of the stripping block and the clamping block are arranged in inclined surfaces, and an air pump is arranged at the upper end of each slide box, a slide plate is fixedly provided on the support rod close to the end of the slide box, and a push spring is connected between the support rod and the slide cavity, a slot is provided on the slide plate, an air pipe is fixedly provided between the air pump and the slide box, and a shovel plate arranged in the same arc as the clamping block is provided at the lower end of the stripping block and the lower end part located at the inner circumferential end of the clamping block.

[0006] The cam is provided with a locking plate, and the locking plate is provided with a locking plate which is fixedly provided with a locking plate, and the locking plate is provided with a locking plate which is locked in a state of being pushed and pulled by the locking plate.

[0007] The beneficial effects of the present invention are:

[0008] Through the circumferentially distributed clamping blocks and the support of the push spring on the support rod, the forging part is centrally positioned in the circumferentially distributed clamping blocks, thereby facilitating the stamping of the forging part by the forging blocks, eliminating the manual positioning process, simplifying the work part and improving work efficiency.

[0009] By clamping the clamping block and the clamping groove, the stability of the clamping block on the stripping block is maintained, thereby reducing the angle between the fitting surface of the stripping block and the clamping block and the horizontal plane. Further, while being able to maintain the support and removal effect for large-mass disc-shaped forgings, the power requirement for the air pump is reduced, saving costs, realizing automatic positioning, automatic clamping, and automatic stripping, and facilitating use.

[0021] Embodiment 1:

[0022] Reference Figure 1-Figure 8According to an embodiment of the present invention, a disc forging workbench includes a forging table 10, a stamping power source is provided at the upper end of the forging table 10, a telescopic gas rod 12 is connected to the lower end of the stamping power source, a forging block 11 is connected to the lower end of the telescopic gas rod 12, and a circumferentially uniformly distributed limiting arc plates 13 are fixed on the upper end surface of the forging table 10, and each of the mutually close parts of the limiting arc plates 13 is provided with a sliding box 14, a sliding cavity 23 is opened in the sliding box 14, and a support rod 15 is slidably matched in each sliding box 14, and a stripping block 16 is fixed on the support rod 15. When the stripping block 16 approaches the end of the forging block 11, a sliding cavity 23 is formed in the sliding box 14, and a support rod 15 is slidably matched in each sliding box 14. A stripping block 16 is fixed on the support rod 15. When the stripping block 16 is close to the end of the forging block 11, a sliding cavity 23 is formed in the sliding box 14, and a support rod 15 is slidably matched in each sliding box 14. There is a clamping block 17, the circumferentially arranged stripping block 16 and the end surface of the clamping block 17 close to the forging block 11 are both arranged in a circular arc surface, the stripping block 16 and the abutting part of the clamping block 17 are arranged in an inclined surface, and an air pump 18 is arranged at the upper end of each slide box 14, a slide plate 20 is fixedly arranged near the end of the slide box 14 of the support rod 15, and a push spring 22 is connected between the support rod 15 and the slide cavity 23, and a slot 21 is opened on the slide plate 20. An air pipe 19 is fixedly arranged between the air pump 18 and the slide box 14, and a shovel plate arranged in the same arc as the clamping block 17 is arranged at the lower end of the stripping block 16 and the lower end part located at the inner circumferential end of the clamping block 17;

[0023] Under the action of the spring support force of the push spring 22, the support rods 15 move closer to the middle end of the forging table 10. Figure 1 As shown, the forging piece is kept still, and the forging piece is placed between the circumferentially evenly distributed clamping blocks 17, so that the forging piece is kept centrally positioned between the circumferentially distributed clamping blocks 17, and the stamping power source at the upper end is operated to make the telescopic gas rod 12 extend and retract up and down, thereby driving the forging block 11 connected at the lower end to move up and down to perform the forging work;

[0024] By increasing the inclined surface between the stripping block 16 and the clamping block 17, the stability of the stripping block 16 and the clamping block 17 is improved to prevent the clamping block 17 from sliding during stamping;

[0025] As the forging work proceeds, the forging piece is deformed by the impact force. Overall, the height of the forging piece becomes lower and the radius of the forging piece becomes larger, so that the forging piece is in contact with the clamping block 17, and an outward pushing force is applied to the support rod 15, pushing the support rod 15 to overcome the spring force of the push spring 22 to slide, thereby driving the slide plate 20 fixed to the end face of the support rod 15 to slide outward. During the sliding process of the slide plate 20, the slot 21 slides with the slide plate 20, so that the air pipe 19 is connected with the slide cavity 23 through the slot 21, and the air pump 18 is controlled to work to fill the slide cavity 23. The gas is introduced to increase the air pressure in the slide box 14, and then the support rod 15 pushes the stripping block 16 and the clamping block 17 to slide inward through the combined force of the air pressure and the push spring 22. The lower end of the forged piece is separated from the upper end surface of the forging table 10 through the shovel plate part at the inner end of the stripping block 16 close to the end of the forging block 11, and the stripping block 16 pushes the clamping block 17 to slide upward through the inclined surface between the stripping block 16 and the clamping block 17, so that the stripping block 16 pushes the clamping block 17 to slide upward, and then the clamping block 17 drives the clamped forging piece to move upward, so that the forging piece can be removed from the forging table 10, completing the forging work.

[0026] Embodiment 2:

[0027] Referring to Example 1, according to a disc forging workbench of an embodiment of the present invention, optionally, a sliding groove 38 is provided on the clamping block 17, a guide slide rod 30 is fixed in the sliding groove 38, a sliding block 29 is slidably matched on the guide slide rod 30, and a reset spring 31 is connected to the upper and lower side walls of the sliding groove 38 and the upper and lower ends of the sliding block 29, and a clamping block 28 is fixed at the end of the sliding block 29 away from the clamping block 17, and a cavity 24 is provided at the mutually close ends of each limiting arc plate 13, and a pressure sensor 25 and a buffer pad 27 that slides together are fixed in each cavity 24, and the pressure sensor 25 and the buffer pad 27 that slide together are fixed in each cavity 24. A buffer spring 26 is connected between the punch pads 27, the clamping block 28 and the buffer pad 27 are arranged flush with each other, the pressure sensor 25 is connected to the air pump 18 through an external controller, a clamping slot 32 is provided between the stripping block 16 and the clamping block 17, a clamping block 33 is fixedly embedded in the clamping slot 32, a plug rod 34 is fixedly provided near the end of the stripping block 16 of the clamping block 33, the plug rod 34 is slidably matched with the stripping block 16, and a spring is connected therebetween, the limiting arc plate 13, and a magnetic cavity 35 is provided at the lower side of the opening 24, a magnetic block 36 is fixedly provided in the magnetic cavity 35, and an inclined end 37 is provided at the inner side of the magnetic cavity 35;

[0028] In the process that the stripping block 16 and the clamping block 17 are squeezed outward by the forging, the stripping block 16 and the clamping block 17 remain in a fixed state under the clamping of the clamping block 33 and the side wall of the clamping groove 32, and the clamping block 17 will not slide upward due to the thrust of the inclined surface abutting against the stripping block 16. The stripping block 16 and the clamping block 17 remain relatively still, and the clamping block 28 connected to the clamping block 17 moves synchronously with the clamping block 17. During the movement, the end surface of the principle forging block 11 of the clamping block 28 abuts against the buffer pad 27 in the cavity 24, and the pig bone buffer pad 27 overcomes the spring force of the buffer spring 26 and moves, so that the pressure sensor 25 is thrusted by the buffer spring 26. When the pressure sensor 25 is connected to the controller, the detection value is transmitted to the controller, and the controller is used for detection and comparison, so that the controller can make the air pump 18 work through electrical connection. When the buffer pad 27 abuts against the card block 28, the card block 28 is embedded in the open cavity 24, and the card block 33 at the lower end of the card block 28 is subjected to the magnetic force from the magnetic block 36. The magnetic block 36 separates the card block 33 and slides into the magnetic cavity 35, so that the card block 33 is separated from the card connection with the clamping block 17, and the insertion rod 34 maintains the sliding cooperation with the stripping block 16. The support rod 15 realizes the inward thrust on the stripping block 16, so that the clamping block 17 is thrust by the inclined surface of the stripping block 16 and slides upward.

[0029] After the forged piece clamped on the clamping block 17 is removed, the clamping block 17 loses its supporting force, and the clamping block 17 slides downward on the inclined surface of the stripping block 16 to reset, and the clamping block 28 is reset by the spring force of the reset spring 31 .
